[QUOTE="Jcalder, post: 5012059, member: 12150"] I found a video on YouTube where some guys shot I think a 16”, 10.5, and a 7.5 over a chronograph. Same ammo. The 16 averaged around 3200, the 10.5 was around 2800 and the 7.5 was around 2450. Opened my eyes quite a bit on how much velocity was lost. But the premise for this rifle is honestly close quarters defense. I don’t have to reach across the county. Therefore the velocity loss isn’t near as critical. If I was building one for a longer range setup I’d look more at a 16 or 20 but for what I want I think the 10.5 is gonna be perfect. Should be a good training rifle for the kids as well [/QUOTE]
